Application filed November 21,1927. Serial 1i 'o.i234,748.'

This invention relates to a safety cock and hasfor its object to provide, in a manner as hereinafter set forth, vice of such class provided with new, original durable, spring controlled, compact, conveniently releasable and thoroughlyeflicient means for latching the Valve plugof the COCk'LWhGIL shifted to closed position jo prevent the accidental opening'of thelatterwi y t i With the foregoingiand otherobjects: in view the invention consists oftheinovel constructiong combinationwand arrangement of parts as hereinafter more specifically described, and illustrated in the accompanying drawings, {wherein isshown an embodiment of the invention, but it is toybe understood that changes, variations rand modifications can be resorted to which fall within thescope 'oftheclaims h'ereunto'appended; I

,Inj the drawings wherein like reference characters V'denote corresponding parts throughout the several views u.-

nFigure' 3 is :a sectional elevation of the safetycock and illustrating the: same: in

Figured is :a section on line4r4' Figure 2.

Referring to the drawings in detail 1 denotes a housing of tubular forinhaving its inner diameter "gradually increasing 3 from its loweritoits inner end and which :provides a chamber 2 for1a-p1ug valvec3 which corresponds inf contour istozithe shape of the chamber 2 and snugly fitss thewall of the latter. The valve 3 has .la' reduced extension 4 at its lower .endiwhich provides 1 a shoulder 5 flush with the bottom edge of the housing 1.".The extension 4' is provided with a in snug fitting engagement with the wall of the chamber 2. The housing 1, at its top, is cut away to the extent of one-fourth of itscircumference to provide aledge 1O anda pair of vertically disposed spaced shoulders 11, 12. The ,shoulders limit the turning action oft-he valve 3 in either direction for a quarter turn thereof. The housing 1 is formed with an intake port 13 which opens into the chamber 2 and an. outlet port 1 1- whichjcommunicates with and extends from i the chamer 2. The housing 1 is furthermore provided with a pair of oppositely disposed lateral extensions 15, 16, the former having a tapered periphery and peripherally threaded as at 1Zfor connection to a gas supply line. o Theextension 16 is of uniform outer diameter and peripherallythreaded as at 17 and engagingtherewithiis an interiorly threaded, flanged leap 19 which projects a substantial distance from the extension 16 and is formed withja jet or discharge open ing 20. a Theexten'sions 15 and 16are tubular andthe inner diameter thereof corresponds to the inner diameter of the intake opening 13andoutletopeningyM respectively. -The outerdiameter o'fthe extensionltl, at its inne'r-end, is less than the outer diameteiw of the extension 15 whereby the flange 21 ofthe cap 1.9 can abut against the periphery ofthe housing 1.; The fiange;2lrof the cap 191 is of polygonal 1 contour. See Figure 11, The valve 3 is formed with a diametrically disposed opening 22,which-is adapted to regis- I ter with the intake 13 and outlet 14 when the cock isinop enposition. The opening port orpassage22 Wlll register with the intake 13 and outlet 143when the valve 3 is given a quarter-turn in a clock-wise direction, as in- 'dicated by the arrow in Figure 4. The

shoulder 11 arrests the shifting movemeiit of the valve 3, when moving in a clock-.visedirection and the shoulder 12 arrests the shifting movement of the valve 3 when it ismoving in an anti-clockrwise direction.

Formed integral with the valve 3 is a stem 23 having a head 24, provided with a counter-sunk socket 25 whereby the wall thereof will form a seat 26. The wall of that part of the socket of smallest diameter is threaded. Extended into the head 24 and bearing against the seat 26 is ahandle member 27 formed at its outer end with a socket 28 and further provided with an axially arranged bore 29 which opens at its outer end into the socket 28., Extending through the bore 29 and threadedly engaging with the threaded wallof the socket 25 is a headed securing device 30 for the handle member 37. The head of said device is indicated at 31and is seated in the socket 28. The bore 29 is of materially less diameter than the diameter of the socket 28 and the head 31 of the device 30 is of greater diameter than'the'bo're29. The

closed position, and said means inclndesm spring controlled latching member36, having one end thereof capable of engaging in an opening 37, formed'in'the housing 1, near the top thereof, andwhen so engaged the valve 3 will be'secured inclosed position. The valve 3 at itstop' is formed with *a diametrically disposed socket 38 opening above the ledgelO, and the'valve 3 is furthermore provided with a diametricallye'xtending opening 39 which communicates with the socket 38. The opening 39 is countersunk as "at e0. The latching member 36 is provided with a peripheral, "annular shoulderel which seatsin the countersink 40' when the member isengaged in the opening 37. Thed'ocking member 36*is* formed at itsouter end witha reduced peripherally threaded extension' l2, which threadedly engages in a socket 43 formed in a'cylindrical member is, provided with'ahe-adea Threadedly engaging with the wall of the socket 38 at the outer end therepf is asleeve 46' having its outer end "opposing" the head 45015 the member 4%." aswell asbeing spac'ed therefrom. Mounted'on' the latching member 36 and interposed between the inner end of the sleeve 46 and the base of the socket 38 is a coiled controllingispring 47. The latching member 36 and cylindrical member 44 bodily move together and shift through the sleeve 46. 'The spring 47 normally tends to maintain the latching member 36in the opening 3'? to latch the valve 3. The

shoulder 4-1 acts to compress the spring 47 when the latching member 36 is shiftedto release position and the shifting of-said member is had through the medium ofa shifting lever 4-8, provided intermediate its ends with a slot et9, through which extends the reduced end 34 "of 'the ar-m 33. I The lever 48' is pivotally connected to there- 'duced end 34: of the arm 33, by the pivot end of-the sleeve 46 and the head 45.

ofthe lever 48 is bifurcated as at 52 for the purpose-of straddling the cylindrical member 44 and is interposed between the outer The spring 47 normally tends to maintain the lever-4'8 inthe position shown in Figures 1 and 2. By pressing the upper end of the lever 48 towards the head 24, the latching member 36 is shifted clear of the opening 37 whereby'the valve 3=can be shifted from closed to open position. It is not necessary to retain pressure onthe'upper end o'f the lever 48 after the member 36 hasibeenmoved clear =of the opening 37. VVhen the valve 33 is inoved in an anti-clock-wise "direction the member 36 snaps into'the opening-37 and latehesthevalve.

:The construction and arrangement :of parts prevent the accidental shiftingof the valve 3 from closed to open position and furthera'ct to maintain theivalve 3 in closed qingto Ilatcli itheplug,= an! arm anchored to .the

stem, and a latching means releasingvlever pivoted intermediatenits ends: andiahaving one end straddling said means in proximity to the outer' end thereof.
